Make sure that your bugs are not on the following list of known issues. You can use your browser's word finder to help search the list.

If the bug is not on the list then please post it in this thread. Attach to your message a screenshot (if possible) and a log file (it's called the "se.log" and is located in the system folder of SpaceEngine's directory). Only the log file will help me to understand your problem and find a solution.

Known Issues

Green items have been fixed for the next release

- Star catalog have many errors in star classification, so there are many "giant dwarfs" and "dwarf giants". - Many real binary stars rendered as single, and many single rendered as binary. This is not a bug. - Ships do not render in the interstellar space - Ships do not render in systems belonging to a star cluster and displayed as "Interstellar" - Few issues with asynchronous loading (stars don't always generate properly, especially when flying to new galaxies) - Holes in some giant stars when camera is directly above a very tall spot [example] - Impossible to find very dim objects (like stellar remnants) in the map mode - Star browser does not detect stars belonging to the central galaxy star cluster and some globular cluster stars - Star browser is not effective at detecting halo stars - In the Map mode, Star browser performing search around camera position, not around the map center - Star browser sometimes shows incorrect star multiplicity data - Flashing landscape LOD on a planet when Wiki for it is displayed - Unfinished text editor for descriptions - When transition from lens flare to star flare begins, the star point turns black and shines through flares/objects when using star style "points". Examples: [1][2] - Unable to select something with cursor for several seconds after repeated clicks sometimes - Star clusters not displayed in Wiki - GUI response issues with some users (interface items glitchy or not respond easily) - GUI toolbars may completely disappear when pressing pin button while half-hidden - Digital value/edit field in planet editor may completely disappear sometimes - Music player doesn't work - Deep space objects (e.g. stars, galaxies) will shine through planets when HDR for DSO is off, but HDR is on and Bloom is on [example] - Comet nucleus star-sprite will shine through planets [example] - Aurora radius limited to planet radius (not a bug, just catalog parameter limitation) - Some neutron stars can have very low temperatures [example] - Flickering flare color in close binary systems [example] - Bugs with some catalog planets with textures from files when using the Editor [example] - Dwarf planets not only generated in asteroid belts - Sunspot distribution is not always realistic - Auto-exposure does not react when a sun is blocked while diffraction spikes are set to normal or super - Planet rings have an unrealistic color palette - "Eclipse bug" on distant planets (weird dark shimmering on outer planet caused by inner planet crossing the sun or two suns eclipsing) - Rounding errors (e.g. 30° in catalog rounds to 29°59'59.99" displayed on HUD) - Shimmering bloom splotch when very close to the surface of a gas giant [example] - Setting StarProcBifurcation to false in the universe config disables generation of all multi-star systems, including procedural - Planets with life are not generated in single-star systems - Cloud cyclones have cut edges sometimes - Galaxy/nebula sprites will rotate when seen from certain angles. This is not a bug. - Level horizon command (End key) doesn't work properly on oblate objects - FOV ignored when choosing default camera position in game mode - Problems when releasing Left+Right click - Solitary brown dwarfs are not generated - The primary planet of a barycenter displays one too many satellites in the Wiki - Wiki displayed luminosity of the Sun as 0.9 - Some bugs with exported surface maps - Auroras and rings can be rendered in front of ships/moons sometimes - Comet tails can be rendered in front of ships/planets - Lens flares are distorted by gravitational lensing (black holes) - Lines or junctures are visible on planetary surface - Problems with shaders loading (disappearing of water, eclipse shadows, etc) - Weird behaviour of Shift-G with star clusters - Switching to fullscreen doesn't work sometimes - Procedural landscape uses only snow detail textures - VSync mode is always Auto (2)

Quote (Red_River) also notice the atmo pressue is unrealistically high. I see this on many terra worlds...

Why couldn't that terra have an atmosphere that thick?

Venus's atmosphere is actually twice as thick as the one in the screenshot, so I don't see an issue with that world. The ones with hundreds or thousands of atmospheres I find somewhat unrealistic, then again, we simply don't know the range that would be typical in nature.

Sometimes the star browser will bug out and not include the multiplicity, planets, and 'with life' data for some stars. Seems to happen after doing it a whole bunch of times or doing a search radius of 100 and there are a thousand it detects.

I found a star that is spinning so fast that it has negative G's at the equator. It should be torn apart because of this.

Ran into another example of this bug, not quite as extreme as the one donatelo found. Also, not sure if it's me or if very oblate stars always have a rotation of two days? In an OB type star pair, both stars had rotations of exactly two days, which seems a bit odd, and no they weren't close orbiting binaries.

Edit: I may be tired, but I'm pretty sure this galaxy isn't supposed to look this colorless. It also looks exactly like a procedural galaxy that I saw which looked the same way. Clearing cache doesn't do anything. Btw, this is one of the galaxies listed in the models text file.

The first time it happened, I thought it was the program glitching out because there was another galaxy that looked ghostly, but was fine after a restart, looks like it's not glitching out this time and it actually is being rendered as almost colorless.

The increased system load when rendering a comet tail is pretty normal, and snowcaps on hot worlds aren't necessarily a "bug", just a shortcoming in the terrain generation code which will probably be refined in the future.
